List自定义对象的两种遍历方式

第一部分

//创建学生类
public class Student {
    //成员变量
    private String name;
    private int age;
    //构造方法
    public Student(){
        super();
    }

    public Student(String name, int age){
        this.name = name;
        this.age = age;
    }
    //成员方法
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "Student{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

第二部分

public class StudentArray {
    public static void main(String[] args){
        //创建集合
        ArrayList list = new ArrayList();
        //赋值
        Student s1 = new Student("小燕子",45);
        Student s2 = new Student("刘亦菲",40);
        Student s3 = new Student("花千骨",38);
        Student s4 = new Student("卓别林",70);
        Student s5 = new Student("周润发",65);
        //给集合添加元素
        list.add(s1);
        list.add(s2);
        list.add(s3);
        list.add(s4);
        list.add(s5);
        //迭代遍历
        Iterator it = list.iterator();
        while(it.hasNext()){
            Student s = (Student) it.next();
            System.out.println(s.getName()+"---"+s.getAge());
        }
        //for循环遍历
        for(int x=0;x<list.size();x++){
            Student s = (Student) list.get(x);
            System.out.println(s.getName()+"----"+s.getAge());
        }
    }
}
